Other Parts Discussed in Thread: DLP6500FYE , TPS65145 Is power up sequence timing depend on external charge pump circuit?
For example, below application note P2, use case of lower Negative Charge Pump.
※Boosting Positive Charge Pump is not use. …
Other Parts Discussed in Thread: TPS65145 , TPS65141 , TPS65140 For TPS65140/TPS65141/TPS65145 datasheet P4, Vref_Typ is written in 1.13V.
Is this typo?
And, correct Vref_Typ is 1.213V, OK?
Best regards,

Dear forum members,
We're having the following issue with our DLP9000 DMD, first half of the image always shows artifacts, it looks…
Hello again User,
It took a little longer to get back to this.
Something is disabling the DC-DC converter TPS65145(U1) since EN_OFFSET is pulled low. I agree that it seems to be working correctly.
Is the resistance measured in point #5 with or without…
That means U1 TPS65145 has gone bad.
Please replace it and don't mount DMD.
Recheck doing same steps to confirm voltages are correct.
Finally remove J3 jumper and mount DMD.

Hello Peihang,
Can you (without touching the DMD board during operation) determine if the noise is from the DMD itself or the PMIC (Power Management IC - TPS65145)?
Is the DMD displaying correctly? Is the noise only noticeable in a quiet environment…
